RATIONALE Early infra-inguinal graft failure, i.e. occurring within 30 days of surgery occurs in approximately 5% of patients16. It is known that the predominant cause of this is thrombosis. The geko™ is an electrical device placed over the common peroneal nerve alongside the knee. The device activates muscle contraction in the peronei using low intensity, low frequency (1Hz) stimulation. The muscle contraction expresses blood from the deep venous system. Application of the stimulation device over the peroneal nerve is suitable for practical purposes. Previous studies have shown that the geko™ substantively increases arterial, venous and microcirculatory blood flow in healthy volunteers. A significant decrease in Tissue Plasminogen Activator antigen has also been demonstrated which indicates increased fibrinolytic activity3. Application of the geko™ device should therefore decrease stasis and increase flow though the graft and as such reduce the risk of thrombosis and as such graft failure.
